Red sea seal going bad?

[deerhunter06]

I picked up a used Red Sea 450 yesterday. The top right side where the sealant is at looks like it could have some air in there. The tank holds water just fine and there is no leaks. Just wondering what you guys think and if anyone has experienced anything similar. I attached two pictures one is left side that looks how I would expect and the other is right side.

If it was any other brand I wouldn’t hesitate filling that tank up. But its a red sea. Hard no for me.

I personally would not chance it (regardless of the brand).

Geez it’s kinda hard to tell if that’s separation or just water drips on the glass. If separation the tank needs to be resealed imo.

I wouldn't use it. And why does the bottom of the tank look like someone dumped a bunch of silicone in?

I've seen a couple posts this past week of red sea tanks with bubbles in the same area - but much smaller. In both cases they were still under warranty and red sea offered to replace both tanks. Red sea must know it is headed to failure. Your picture looks much worse

sometimes the aquarium mats look like that, bit of air between the mat and glass

I asked same thing, he said he put a black bottom in it then later removed it. They definitely didn’t skimp on the silicone.

It’s definitely separation, finally just dawned on me to simply push on it to see if it goes away. It does.

Hard no from me. That’s a big section with silicone barely making connection.

Did the seller point it out to you? Seems sketch if they sold it to you like that!

Knowing the history of these separations with Red Sea, this would have been the first thing I looked at before buying used. I hope you got a good deal, cause if you can’t return it, it needs repair. Reseal is a quick fix but not a guaranteed one. Silicone is inert, new silicone will not bond to existing cured silicone, and if even a microbubble is left in between, this will be a point of future failure. Best, Buy hard way, is to carefully disassemble, clean and rebuild the whole tank professionally.

I saw it, he said it held water, which it does. I really wanted it. Didn’t really think it through.
